Counter Dividers Procurement Notes

Verify component authenticity through authorized Harris Corporation or Texas Instruments channels. Confirm package integrity and pin alignment for the 16-CDIP format. Ensure environmental ratings match specific operational requirements given the wide temperature range. Request detailed datasheets to validate electrical characteristics against system specifications before integration.

Counter Dividers Selection Notes

Select this component for applications requiring robust, high-speed binary counting in harsh environments. The ACT series offers superior speed compared to standard AC logic. Consider the 16-CDIP package for through-hole mounting needs. Verify power supply stability within the 3 V to 18 V range to ensure reliable synchronous operation and proper reset functionality.

Counter Dividers Part Context

This part belongs to the Harris Corporation ACT series of high-speed CMOS logic devices. Harris was acquired by Texas Instruments, which continues to support these legacy military-grade components. The CD54 prefix indicates a military temperature range and reliability standard, distinguishing it from commercial variants.

Counter Dividers Replacement Considerations

Check for direct equivalents such as the CD54ACT191F3A from other manufacturers like Texas Instruments. Ensure pin compatibility and electrical parameters match exactly. Verify that any substitute maintains the same synchronous bidirectional counting behavior and asynchronous reset capabilities.
